Changing directory within a bash script

Question

I am right now running a bash script in which i need to change my directory and execute a script from the changed directory.

I want to change my folder to myfolder and run script.sh into that particular folder.

Any way to do that in Bash?

I have already tried

cd myfolder
./script.sh

But that does not work.

That works for me. And everyone else ever. What about it is not working? Are you getting an error message? — rjmunro

I think what he means to tell is if he runs the code from one bash script to execute another bash script which is in another directory. — Subho Halder

@aditya.gupta Try adding the following flags: -xv at the top of the script and post your error. Add those flags right aftr #!/bin/bash so like this #!/bin/bash -xv

Sorry if it doesn't work. You should have mentioned it in your question that you had already tried it before.

@aditya.gupta: This is in essence the same as the one you already tried. The aspects in which it differs are not mentioned as issues in your question.

Where is script.sh located? I'm curious about how this works.

Subho Halder Over a year ago

@octopusgrabbus script.sh is located inside myfolder, since in a bash script if you just write cd myfolder and in the next line write ./script.sh then it wouldn't work. I hope you get it :)

Thanks; got it. That's what I thought was happening.

Why not simply try this:

cd /absolute_path/myfolder
./script.sh

Specifying the absolute path makes this independent from where the script is issued.

Maybe its because the other script in "myfolder" does not have permisions to execute.

cd myfolder
chmod 755 myscript
./myscript.sh

Had already made it executable. Anyways, this was the code which made it work (cd myfolder && ./script.sh)

Florin Stingaciu Over a year ago

That doesn't make any sense. It's all the same

aditya.gupta Over a year ago

Nopes. Try it yourselves. echo "Initially" pwd cd /anotherfolder pwd

Florin Stingaciu Over a year ago

@aditya.gupta Did you have the line #!/bin/bash at the top of your script?

Florin Stingaciu Over a year ago

@aditya.gupta Well obviously you did something wrong. We're talking about the most basic commands of bash scripting.

Where is the script located in relation to myfolder? All these answers posted should work. For instance, if myfolder is in root, and the script is in /path/to/file.sh you would need to escape first.

cd ../../myfolder
./script.sh

You could check this too by putting an ls in your script. If you don't see myfolder then you're in the wrong spot.

Is your script executable? Try a chmod +x script.sh and run it again.

What error messages are you getting?
